Fireye Nexus

Fireye is a leading manufacturer of flame safeguard controls and burner management systems for commercial and industrial applications throughout the world. Our products can be found in a variety of public buildings, commercial properties, power plants, pulp and paper mills, petrochemical facilities and food processing plants. Fireye is a part of Carrier (NYSE: CARR). Our roots go back to the 1930s, when the company offered the first commercial/ industrial electronic flame safeguard control, a photoelectric device designed to detect the presence of an oil flame in less than a second. We were the first to develop infrared scanners to monitor gas and oil flames, the first to develop a scanner that discriminated between signals from adjacent burners, the first to create a completely solid-state programming control. We have set new standards with a micro-processor-based, auto diagnostics program that communicates in five different languages.
